Definitions
- the invention relates to a cyclone classifier with an elongated, essentially vertically extending housing, the upper area of which is equipped with a carrier gas / product inlet, with a classifier and with a carrier gas / fine material discharge and in the lower region of which there is a coarse material discharge.
- the invention has for its object to improve the classification of a Zyk Ions of the known type.
- This object is achieved in that a central, essentially axially extending installation is arranged in the housing of the cyclone sifter, the carrier gas / particles directed downward in the peripheral area and upward in the central area, in the central area separates currents. Controlled flow guidance is achieved by installing this type. The sighting in the area in which the downward peripheral flow merges into the upward central flow (deflection direction) is significantly improved.
- there is a defined distribution of solids in the classification zone This results overall in the desired improvement in the classification, which is reflected, among other things, in better coarse and fine application.
- FIG. 1 shows a cyclone sifter, partly in view and partly in section.
- the cyclone classifier 1 shown the housing of which is designated by 2, comprises an upper region 3, which is connected to the carrier gas / product inlet 4, the classifier 5 (only the classifier wheel 6 of a dynamic classifier is visible) and the carrier gas / Fe ingut- discharge 7 is equipped.
- the upper region 3 is followed at the bottom by the housing section 8, which is typical for cyclone separators and tapers downwards. This merges into a cylindrical section 9, the lower end of which forms the coarse material discharge 11 (shown only by an arrow).
- the installation designated 12. It is rotationally symmetrical and extends concentrically to the longitudinal axis 13. Its lower end is in the area in which the peripheral, downward gas / particle flow merges into the central, upward flow. Its upper end lies directly under the classifier wheel 6.
- the installation 12 comprises three sections. Its lower section 14 is tapered in the direction of flow. Its central section 15 has a cylindrical shape. Its upper section 16 widens conically in the direction of flow.
- the carrier gas / particle currents forming during the operation of the cyclone ionizer 1 are indicated by arrows 23.
- the carrier gas / product mixture flows tangentially into the upper section 3 of the housing 2 from the inlet 4 arranged at the level of the classifying wheel 6, expediently at least partially above the classifying wheel 6. From there, it flows downward outside the installation 12 in a spiral. A deflection takes place at the level of the lower edge of section 14, which causes an effective deflection sighting. Coarse material arrives at the coarse material discharge 11. entrained particles enter the ring channel 18.
- the mouth of the ring channel 22 in the upper section of the installation 12 forms an annular nozzle which distributes the mixture in a defined manner in the inlet area of the classifier wheel 6. Particles passing through the classifier wheel enter the fine material discharge 7 with the carrier gas. Particles flung outwards from classifier wheel 6 enter the peripheral downward flow and are sighted and classified again.
- the suction effect in the region of the entry of the mixture into the cylindrical section 15 of the installation 12 can be significantly increased by admission of secondary air.
- the secondary air is supplied in such a way that the entry into the cylindrical section 14 is designed in the manner of an injector.
- a secondary air line 24 is provided, which enters the housing 2 through the lower section 9 and penetrates the lower installation body 17 in such a way that its Mouth 25 lies in the end face of the installation body 17 facing the constriction 19.
- the supply of secondary air at this point results in an injector effect which increases the suction effect and which results in a further improvement in the visibility and classification properties.
